Change NODE layout for pattern matching

I prefer pconst to be the first element of NODE.

  Before:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | imemo  | imemo  | pkwargs
    u2 | pconst | pconst | pconst
    u3 | apinfo | fpinfo | pkwrestarg

  After:

       | ARYPTN | FNDPTN | HSHPTN
    ---+--------+--------+-----------
    u1 | pconst | pconst | pconst
    u2 | imemo  | imemo  | pkwargs
    u3 | apinfo | fpinfo | pkwrestarg
